Can You Drink Tap Water in Ventura?

Yes, Ventura's tap water is generally considered safe to drink as Ventura has no active health based violations of the Safe Drinking Water Act (SDWA) that we are aware of. Other factors such as lead piping in a home, or low levels of pollutants on immunocompromised individuals, should also be considered, however. To find more recent info we might have, you can check out our boil water notice page, the city's water provider website, or Ventura's local Twitter account.

According the EPA’s ECHO database, from April 30, 2019 to June 30, 2022, Ventura's water utility, Ventura Water Department, had 0 violations of the Safe Drinking Water Act. For more details on the violations, please see our violation history section below. The last violation for Ventura was resolved on Sept. 30, 2018. This assessment is based on the Ventura Water Department water system, other water systems in the city may have different results.

While tap water that meets the EPA health guidelines generally won’t make you sick to your stomach, it can still contain regulated and unregulated contaminants present in trace amounts that could potentially cause health issues over the long-run. These trace contaminants may also impact immunocompromised and vulnerable individuals.

The EPA is reviewing if it’s current regulations around pollutant levels in tap water are strict enough, and the health dangers posed by unregulated pollutants, like PFAS.

Water Quality Report for Ventura Tap Water

The most recent publicly available numbers for measured contaminant levels in Ventura tap water are in its 2020 Water Quality Report. As you can see, there are levels which the EPA considers to be acceptable, but being below the maximum allowable level doesn’t necessarily mean the water is healthy.

Lead in tap water, for example, is currently allowed at up to 15ppb by the EPA, but it has set the ideal goal for lead at zero. This highlights how meeting EPA standards doesn’t necessarily mean local tap water is healthy.

EPA regulations continue to change as it evaluates the long term impacts of chemicals and updates drinking water acceptable levels. The rules around arsenic, as well as, lead and copper are currently being re-evaluated.

There are also a number of "emerging" contaminants that are not currently. For example, PFAS (Per- and polyfluoroalkyl substances), for which the EPA has issued a health advisory. PFAS are called "forever chemicals" since they tend not to break down in the environment or the human body and can accumulate over time.

We recommend looking at the contaminants present in Ventura's water quality reports, or getting your home's tap water tested to see if you should be filtering your water.

Ventura Tap Water Safe Drinking Water Act Violation History - Prior 10 Years

Below is a ten year history of violations for the water system named Ventura Water Department for Ventura in California. For more details please see the "What do these Violations Mean?" section below.

From July 1, 2018 to Sept. 30, 2018, Ventura had 1 health-based Safe Drinking Water Act violation with the violation category being Maximum Contaminant Level Violation, more specifically, the violation code was Maximum Contaminant Level Violation, Average which falls into the Disinfectants and Disinfection Byproducts Rule rule code group, and the Stage 2 Disinfectants and Disinfection Byproducts Rule rule code family for the following contaminant code: TTHM.

From April 1, 2015 to June 30, 2015, Ventura had 1 health-based Safe Drinking Water Act violation with the violation category being Maximum Contaminant Level Violation, more specifically, the violation code was Maximum Contaminant Level Violation, Average which falls into the Disinfectants and Disinfection Byproducts Rule rule code group, and the Stage 2 Disinfectants and Disinfection Byproducts Rule rule code family for the following contaminant code: TTHM.

From Jan. 1, 2015 to March 31, 2015, Ventura had 1 health-based Safe Drinking Water Act violation with the violation category being Maximum Contaminant Level Violation, more specifically, the violation code was Maximum Contaminant Level Violation, Average which falls into the Disinfectants and Disinfection Byproducts Rule rule code group, and the Stage 2 Disinfectants and Disinfection Byproducts Rule rule code family for the following contaminant code: TTHM.

Is there Lead in Ventura Water?

Based on the EPA’s ECHO Database, 90% of the samples taken from the Ventura water system, Ventura Water Department, between sample start date and sample end date, were at or below, 0.0022 mg/L of lead in Ventura water. This is 14.7% of the 0.015 mg/L action level. This means 10% of the samples taken from Ventura contained more lead.

While Ventura water testing may have found 0.0022 mg/L of lead in its water, that does not mean your water source has the same amount. The amount of lead in water in a city can vary greatly from neighborhood to neighborhood, or even building to building. Many buildings, particularly older ones, have lead pipes or service lines which can be a source of contamination. To find out if your home has lead, we recommend getting you water tested.

No amount of lead in water is healthy, only less dangerous. As lead accumulates in our bodies over time, even exposure to relatively small amounts can have negative health effects. For more information, please check out our Lead FAQ page.

Are there PFAS in Ventura Tap Water?

Currently, testing tap water for PFAS isn’t mandated on a national level. We do have a list of military bases where there have been suspected or confirmed leaks. There appears to be at least one military base - Naval Construction Battalion Center Port Hueneme - near Ventura with suspected leaks.

With many potential sources of PFAS in tap water across the US, the best information we currently have about which cities have PFAS in their water is this ewg map, which you can check to see if Ventura has been evaluated for yet.

Our stance is better safe than sorry, and that it makes sense to try to purify the tap water just in case.

What do these Violations Mean?

Safe Drinking Water Act Violations categories split into two groups, health based, and non-health based. Generally, health based violations are more serious, though non-health based violations can also be cause for concern.

Health Based Violations

  1. Maximum contaminant levels (MCLs) - maximum allowed contaminant level was exceeded.
  2. Maximum residual disinfectant levels (MRDLs) - maximum allowed disinfectant level was exceeded.
  3. Other violations (Other) - the exact required process to reduce the amounts of contaminants in drinking water was not followed.

Non-Health Based Violations

  1. Monitoring and reporting violations (MR, MON) - failure to conduct the required regular monitoring of drinking water quality, and/or to submit monitoring results on time.
  2. Public notice violations (Other) - failure to immediately alert consumers if there is a serious problem with their drinking water that may pose a risk to public health.
  3. Other violations (Other) - miscellaneous violations, such as failure to issue annual consumer confidence reports or maintain required records.

COVID-19 (CORONAVIRUS)

Ventura’s water supply meets all stringent state and federal drinking water requirements. COVID-19 has not been detected in drinking water and will not affect water supply. In adherence to California Drinking Water Standards Ventura Water’s treatment processes includes membrane filtration and disinfection which remove and kill 99.99% of viruses, including COVID-19, bacteria and other pathogens. Ventura Water owns and operates a full scale, State- certified laboratory and also uses outside State-certified labs to monitor water quality.

For more water quality information on COVID -19 visit:

WATER QUALITY FLUSHING NO-DES

The City’s water service area is a complex system of more than 390 miles of pipelines with a total storage capacity of approximately 52 million gallons in 32 tanks and reservoirs providing water to residents and businesses. Water main flushing is a necessary part of operating and maintaining a drinking water distribution system to ensure high quality drinking water.

Routine maintenance is required to:

  • Maintain water quality
  • Clean water mains
  • Maintain proper distribution operation
  • Flush dead ends
  • Maximize pipe lifespan
  • Conduct fire flow tests

To save water, Ventura Water invested in a state-of-the-art flushing unit called the NO-DES (Neutral Output Discharge Elimination System) truck. The unit filters and recirculates water within the distribution system, saving thousands of gallons of clean drinking water from flushing to residential streets.

STATE WATER INTERCONNECTION PROJECT

The California State Water Project (SWP) is a water storage and delivery system of reservoirs, aqueducts, power plants and pumping plants extending more than 700 miles—two-thirds the length of California. To date, the City has not received direct delivery of its annual State Water Project allocation due to a lack of infrastructure. The nearest SWP wholesaler to the City is Calleguas Municipal Water District (Calleguas). The joint agencies, which include the City, Casitas Municipal Water District, and United Water Conservation District, are currently working with Calleguas to develop an interconnection to allow for delivery of their SWP allocations. The interconnection project will include a pipeline used to transport water between Calleguas and the City’s water distribution systems to improve regional water supply reliability.

VenturaWaterPure | Potable Reuse

The VenturaWaterPure Program will diversify Ventura’s water supplies through innovative water treatment technologies. The proposed program includes an Advanced Water Purification Facility (AWPF) for potable water reuse. It will create a locally owned source of highly purified drinking water that provides Ventura with a long-term drought-resilient water supply.

EDUCATIONAL INFORMATION

Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the U.S. EPA’s Safe Drinking Water Hotline (1-800-426-4791)

The sources of drinking water (both tap and bottled water)

include rivers, lakes, streams, ponds, reservoirs, springs and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity. Contaminants that may be present in source water include:

  • Microbial contaminants, such as viruses and bacteria that may come from sewage treatment plants, septic systems, agriculture and livestock operations and wildlife.
  • Inorganic contaminants, such as salts and metals that may be naturally occurring or result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining or farming.
  • Pesticides and herbicides from a variety of sources, such as agriculture, urban storm water runoff and residential uses.
  • Organic chemical contaminants, including synthetic and volatile organic chemicals that are by-products of industrial processes and petroleum production, and can also come from gas stations, urban storm water runoff, agricultural applications, and septic systems.
  • Radioactive contaminants that can be naturally-occurring or be the result of oil and gas production and mining activities.

If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. Ventura Water is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at: http://www.epa.gov/lead

In order to ensure that tap water is safe to drink, the U.S. Environmental Protection Agency (USEPA) and the State Water Resources Control Board (SWRCB), Division of Drinking Water (DDW) prescribe regulations that limit the number of contaminants in water provided by public water systems. Department regulations also establish limits for contaminants in bottled water that provide the same protection for public health.

Some people may be more vulnerable to contaminants in drinking water than the general population. Immunocompromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS

or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. USEPA/Centers for Disease Control (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline: 1-800-426-4791

Ventura Water conducted a Source Water Assessment (DSWAP) in 2013 for each of the drinking water sources serving the Ventura Water system. Sources in this system are considered most vulnerable to the following activities: gas stations, automobiles repair shops, sewer collection systems, and metal manufacturing. Contaminants associated with these activities have not been detected in the water supply.
